ln the practice of our invention, we provide a furnace a composed of anouter metallic wall or casing a2 and provided with an inner lining offire brick, and the furnace a. is supported by legs a4.

Within and resting on the bottom of the furnace chamber c5 is a gas andairburner b of any suitable constrinftiou, and with which is connectedtwo pipes b2 and 3 one of which is designed to supply gas and the otherair to the burner b, and said pipes are preferably passed through thebottom of the furnace casmg and are provided respectively withextensions b4 and 0" having valves Z1 and b?. The burner .7) ispreferably composed of parallel pipes bs connected by cross pipes b9,but any Suitable burner adapted for the consumption of gas and air maybe employed.

Within the top portion of the furnace is placed a retort receptacle c,and passing upwardly through the bottom thereotl is a cylinder c2 inwhichV is mounted a piston c3. Thev cylinder c2 is provided in one sidethereof and adjacent to the bottom of the retort receptacle c with anopening c4, and at the bottom end of said cylinder is a forwardlydirected pipe c5 which communicates therewith and extends through thefront wall of the furnace, and which is controlled by a valve d which isconical in form as shown in Fig. 2 and provided in one side with atransverse port d2, and the valve (Z is provided with a rod d3 whichpasses out through one side of the furnace wall and with which isconnected an arm d4. A bracket arm d5 is connected with the furnacecasing or wall and passed through the end thereof is a set screw al, anda spring (Z7 is placed between the inner end of the set screw d and theouter end of the valve rod cl3, and this spring presses on the end ofsaid valve rod and serves at all times to hohl the valve al firmlyseated and the tension of this spring may be regulated at any time bymeans of the screw (ZG.

The entire machine is preferably supported in or by a suitable base panc with the frontportion of which are connected upright supports e2, andconnected with the front wall `of the furnace above the pipe c and withthe top of the supports c2 are rods or bars f which are angular in crosssection and on which are mounted sleeves f2 which are. movable thereonand with the inner ends of which is connected a mold jaw f3. `Anothermold jaw f4 similar in form to the mold jaw f3 is mounted on the sleevesf2 and provided with sleeves f5 which are movable on the ygleeves f2,and while the `mold jaw f3 is movable on the rods or bars f the mold jawf4 is movable on the sleeves f2. The mold jaws f3 and f4 are provided intheir inner faces with mold chambers or recesses f whichare the counter'arts of each other, andwhen'thelsaidmoldp jaws are placed togetherlrinithe'operation of the machine as he` afterkdescribed, the chambers orrespooI-vs aped; inf .form as clearly shown in Fig. 6, andsaid'm'oldjaws are'provided adjacent to one end of said mold withvatransverse aperture fs Which-*Communicates with the mold chamber and isangular in shape in cross section in the form of construction shown. Themold jaw f* is provided with two forwardly directed arms g and yg2provided respectively with longitudinal slots g'a and g4, and a leverg5- is pivoted to the arm g by means of a bolt g which passes throughthe slot g3 and is provided with-a nut gT and the position of the leverg5 may be adjusted on the arm g by means of the said bolt and nut. Thearm g2 is slotted horizontally as shown in Fig. l, and the lever gl5passes therethrough, and pivoted to said lever between the arms g and g2is a link h provided with a pin 11,2 on which -is mounted a horizontalbar h3 which ranges backwardly and is adapted to enter and pass through'the transverse aperture f8 `in the mold jaws f3 and f4, and the mold jawf* is provided with a thimble h* into which the bar h3 passes and whichserves as a guide and support for the rear end thereof.

Mounted on the front end portions of the A sleeves f2 is a rock shaft c'with which is connected a lever 2, and said shaft is provided withdownwardly and backwardly directed arms 3, and mounted between thesleeves f5 is a rod 4 with which are connected links 5 which are alsoconnected with the arms i3 of the shaft z'. On the front ends of thebars are placed keepers j with which is connected a transverse roc;A '52provided with a lever ja, and mounted between the front ends of thesleeves f2 is a rod j* with which are connected links js, and the rod jzis provided with arms j with Awhich said links are also connected.

`The front end o f the pipe c5 is providedwith a conical or taperednozzle c and the mold jaw f3 at the inner end of thetransverse aperturef8 is provided with a corresponding conical recess c7, and bymanipulating the levers 2 and 3 the mold jaws f3 and f4 may be throwninto. the position shown in Figs. l and 6, in which position theaperture f8 in the mold jaws f3 and f4 will register with the bore ofthe pipe c5 and a communication between the cylinder c2 and the moldchambers or recesses f6 in the mold jaws f3 and 7'* will be established.

Supported above the furnace ais a shaft 5f,

said shaft being preferably supported by a hanger or hangers k2 only oneof which is shown, and adjacent thereto is another hanger or support k3in which is mounted a crank shaft 7a4, this construction being form amold chamber f. which 'is' dearly Shown in Fig- 7 and partiallushoviiiiin. Ivig. 1; The crank s haff, kr is provided ed by a wrist pin m2 withwhich is connected* a crank pin m3 provided with a tubular head m* intowhich passes a longitudinallyv mov- `with a large crank disk la having acrank pin lc with which is connected a crank rod l able pin fm,6provided with a pivoted keeper m". Placed in the tubular head fm,4 ofthe crank pin m3 is a spiral spring m7, this construction being clearlyshown in Figs.- l and 7 and the pin m5 is provided with a stop maonwhich the spring 'mi' bears. The piston c3 in the'cylinder c2 isprovided with a rod n with which are connected links fn?, and pivotedover the' front wall of the furnace at n3 is a lever n4 with whichtheflinks n2 are connected at n, and the lever at* ranges backthe keeperm6. The arm d* which is 'connected with the valve rod d3 passes throughthe link device las as clearly shown in Figs.`1 and 7 and with thisconstruction it will be seen that the operation of the crank shaft le*results in the operation of'both the lever n4 and the arm d4 by whichthe piston c3 and the valve ai are operated. The outer crank disk m onthe crank shaft k* is provided with a conical clutch member o in whichis placed a' spiral spring o2, and said crank disk fm, is provided witha recess 03 adapted to receive the corresponding end of the shaft 7c asclearly shown in Fig. 7 and mounted on said shaft is a supplementalclutch membero4 which is movable longitudinally of said shaft.-

Mounted on the shaft if: vadjacent to the hanger 7a2 is a sleeve p towhich is pivoted a lever p2, and connected with said lever is a link p3which is connected with a supplemental sleeve p4 slidably mounted on theshaft c and by means of which the clutch back wall, is provided with aside opening o" through which the burner or the condition of the furnacechamber may be examined, and by means of which, or through which theburner may be ignited, and in the top portion of said wall of thefurnace is an escape flue or passage 712 through which the products ofcombustion may pass.

Pivoted to the imier end of the arm g2 which is connected with the moldjaw j* is a rotatable stop or regulating device a, the connection ot'which ivith said arm is made by means ofA a bolt or screw s2 passingthrough the slot g* and provided with a mit whereby the stop o1'regulating device s .may be adjusted longitudinally of said arm ifdesired. and this device is intended to regulateV the operation of thelever f/5 as hereinafter described.

It will be understood that the nioldclianiber formed by the separateparts f in the mold jaws f and f4 may be of any desired shape accordingto the article which it is de.- sired to cast. and the operation of ouriinproved casting machine will be readily un ders-total from theforegoing description when taken in connection with the accompanyingdrawings and the following statement thereof.

This machine is particularly designed for casting various articles fromwhat are known as sot't or comparativcly soft metals which will meltquicker than steel or cast iron. and in practice the metal or metals tobe melted and t'roni which the` castings aie to be made are placed intl'ie retort receptacle c and the bi-irner is ignited. `The moltenmetal. as will be understood. passes into the cylinder c'` through theopening or aperture. c* aiid into the pipe the valve therein beingnormally closed. `At this stage ot' the procedure the lever f/fvisoperated to withdraw the bar li. into the position shown in Figs. 1 and6.

j The lever i is then moved in the direction ot the arrow m2. Thisoperation forces t-lie mold jaw f* into ctiiinection with( the mold jawf as shown in Figs. 1 and (i. and the t'orm aiid construction of theariii i and lilik 'if' is such that this operation will lock the jaws fand f* together. The lever j is then moved in the direction of the arrow.r1 aiid this forces the jaw f3 with the jaw f* locked thereto into theposition shown in Fig. 1. in which position the conical nozzle c at thecud of the pipe c eiitei's the corresponding recess c7 in the jaw f andthe coiiiiiiiiuicatioii between the pipe ci and the mold chamber in thejaws f" and f* is established. the position ot' the jaws 7' and f* atthis time with reference to each other being clearly sliziwn in Figs. 1and (i. The lever p2 is then operated to throw the clutch members o ando* into engag g'ementI and the crank shaft r* is turned. At thebeginning of this movement of the ci'aiik shaft. the arin J* which isengaged with the large crank disk is operated to open the valve and at.the saine time the, piston c which is operated b v or from the smallcralik disk m begins to ino've. The pressure et the piston c on themolten metal in the lower end ot the cylinder c' is notl exerted untilthe aperture c* is entirely closed. and at this time the. valve (lv dhas been opened, the mold chamber in the jaws f3 and f* filled and thevalve al reclosed and the piston c raised to its highest position. Thelever j is then operated in the direction of the arr.iw .c4 to Withdrawthe mold jawsl f and f* while still locked together from engagement withthe pipe (-5. after which the lever y is thrown into the positionindicated at .1/ in Fig. 6, in which position ot' said lever the bar11.3 is thrown backwardly until the end thereof reaches the. positionshown at '1/1 in said figure'. This cleans ott' the surplus metall atthe end ot' the casting in the mold chamber f7, and when the metal haspartially cooled the lever yf" is forced into the position shown at y inFig. and this operation forces the bar li: entirely through the mold jawf and cleans out the recess c7, or forces out any niet-al which may havelodged in said recess.

lt will be understood that the stop device .s' is turned into theposition shown in dotted lines in Fig. 6 to limit the first movement ofthe lever y" as above described, after which said stop device is turnedinto the position shown in full lines in order that the lever g may bemoved into the second position above described, or that shown at 1/2".After the operation of the lever y as and for the purpose abovedescribed. the lever 'i2 is moved backwardly or in the direction of thearrow fr', and this operation results in separating the inold jaws f andf4. and the, casting is dropped out and falls into the base pan c oftheframe or into any suitable receptacle prepared therefor.

The object of the spring attachment by means of which the pin mf" isconnected with the crank rod mi* as shown in Fig. l. is to cushion thepiston c in its downward move meut and to prevent. a too great or toosudden pressure or shock being applied to the molten metal within the.cylinder r2, and the consequent injury to said cylinder and itsconnections which might result especially when said parts are highlyheated. The link or keeper devices m and v which are connected with the'lever 11,4 and the aiiii (14 respectively and by means ot which saidlever and arm are operated are adjustable on said lever and arm. and bymeans of this coi-istruction the. interval of time between the operationot' said arm and said lever may be l Fegulated. lt. will lie seen thatthe lower end of the cylinder c2 and the pipe or passage way c aredirectly over the burner or in the bottoni part of the furnace chamber,and by means of this construction or location of r I said parts, themolten metal in the said cylinderand in the said' pipe is highly heatedand maintained in a liquid condition so that it flows more freelythanwould otherwlse be possible, and this facilitates the operation' of theapparatus as hereinbefore described and also enables the apparatus towork with a less degree of heat or less consumption of fuel than wouldotherwise be possible.

ln Figs. S) 'and `l() we have shown a modification in which the jawmembers f and f4 of thc mold device are provided respectively withsupplemental jaw members u and fu?, which are dctaclmhly connectedtherewith by means of screws, bolts or other devices a3 and u, and whenthese supplemental jaw members are employed the mold recesses fcomposing the moldchamber f7 are formed therein, and 'the transversepassage ways f8 extend therethrough, and the bar h5 is mov- Vabletherethrough and the reason for provid-y ing the supplemental jawmembers u and u2 is to provide `means whereby different forms and sizesof molds may be employed whenever desired by simply substituting one setof the supplemental jaws u and u2 for another. The operation with thisform of construction will be exactly the same as with that shown in l*lgs. 1 to Sfinclusive. The reason for forming the valve dwith atransverse port or passage in one side thereof only, is to provide meanswherebysaid valve will clean itself every time that it is turned back toclose the tube or tubular passage way c5, this operation beingaccomplished by reason of the fact that the molten material between thevalve and the cylinder c2 in the reduced passage way or tube c5 ishighly heated at all times when the apparatus is in operation.

The furnace, or the details of the construction thereof, and the meansfor operating the piston c3 and the valve d and the burner l) form nopartof the invention described and claimed herein, but are made thesubject ofa prior application filed by us April- 19, 1909, Ser. No.490,716.
